Abstract

이 발명은 수온 센서 고장시 수온 진단 장치 및 그 제어 방법에 관한 것이다. 공기의 온도를 감지하는 흡기온 센서, 상기 흡기온 센서로 부터의 공기 온도의 신호를 전달 받아 수온값을 계산하는 엔진 제어 장치, 상기 엔진 제어 장치로, 수온값의 신호를 입력받아 출력 크기를 결정하는 엔진을 포함하고 있다. 동작의 필요한 전원이 공급되면, 먼저 수온 센서의 상태를 판독하여 판독된 수온 센서의 상태로 수온 센서가 고장인지의 여부를 판단하고, 수온 센서가 고장이라고 판단되면, 흡기온 센서로 부터의 온도 신호를 전달받아 엔진 제어 장치에서 수온을 보정하여 수온에 의해 엔진을 제어한다.The present invention relates to an apparatus for diagnosing water temperature and a control method thereof when a water temperature sensor fails. Intake temperature sensor for sensing the temperature of the air, the engine control device for calculating the water temperature value by receiving a signal of the air temperature from the intake temperature sensor, the engine control device, the output size is determined by receiving a signal of the water temperature value It includes an engine. When the required power for operation is supplied, the state of the water temperature sensor is first read to determine whether the water temperature sensor is in a fault state, and if the water temperature sensor is in fault, the temperature signal from the intake air temperature sensor. The engine is controlled by the water temperature by correcting the water temperature in the engine control device.
